Abstract: Snow stop includes a base member, and a snow-restraining member. The snow stop can have a series of holes for ventilation of adhesive as well as for forming “glue-rivets” with cured adhesive, and can have slots (grooves) to the holes or boundary of the snow stop to assist in ventilating adhesive solvent. The holes and grooves also can provide for increased physical bonding with the adhesive and hence, roof. The base may be round with the snow-restrainer included in intersecting upstanding members.

Abstract: A roofing system has a sheet surface which may include standing ridges or batten ridges, and the sheet surface has a predetermined arrangement of three dimensional features in addition to the standing ridges or the batten ridges. A snow stop may be installed in conjunction therewith, and may have lower protrusions which may be generally complimentary thereto and/or a snow wedge so as to further help keep it from being disengaged by typical shear and/or peel forces after installation. Thus, for example, as with aluminum or steel standing seamed roofs, added fence type snow guards with their brackets and so forth can be avoided, and/or individual snow stops can be installed so as to have greatly increased holding power to the roofing surface, even in notable cases when applied by underskilled workers.

Abstract: A new snow stop includes a base, a support projecting from the base, and a restraining member attached to or made integral with and part of the support, wherein the base has a support opening therein, and the support is formed from a suitable foldable stock and is attached to the base, the support having a leg which projects upwardly from the base and which thrusts through the support opening of the base, and the support having a foot which lies underneath the base and which extends outwardly of the support opening of the base. A method to make the snow stop includes providing an intermediate restraining member and support having an extended leg with enough suitable foldable stock to provide a foot, inserting the extended leg of the intermediate through a support opening of a base, and folding the suitable foldable stock inserted therethrough to provide a foot of the support. Use of the snow stop can include attachment to a roof.
